项目摘要
With rapidly expanding digitized text archives such as social media, news, and medical records, researchers are eager to measure the composition, behavior, and worldviews of diverse human populations through their linguistic expression. But it is still unknown how to construct robust and fair aggregation of text-based signals for downstream analysis. This Faculty Early Career Development project's goal is to develop fair and uncertainty-aware text analysis methods to measure socially relevant topics, sentiment, and events across bodies of text, in order to infer their relationships with variables such as author demographics, health outcomes, and political conflict. These methods will be more accurate - and be self-aware when they make mistakes - for applications such as tracking events in the news, or understanding sentiment from social media.Current methods for text aggregation are systematically biased towards idiosyncrasies in their training data, and are confounded by variability in natural language processing errors across social variables of interest. Furthermore, new probabilistic inference methods may aid insight by incorporating more richly structured natural language analysis, such as entity coreference, event parsing, or structured sentiment analysis. Through a series of case studies in the social and health sciences, this project will develop better statistical and linguistic models that combine probabilistic generative and discriminative approaches to text modeling. These methods will more accurately measure social variables' effects on topics, sentiment, and events, while inferring confidence intervals and other important statistical measures of uncertainty. Finally, this project will support education and training in interdisciplinary computational social science, through workshops at both undergraduate and graduate levels, targeting students from areas including computer science, linguistics, political science, and African-American studies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
随着社交媒体、新闻和医疗记录等数字化文本档案的迅速扩大,研究人员渴望通过语言表达来衡量不同人群的组成、行为和世界观。但如何构造鲁棒、公平的文本信号聚合以供下游分析仍然是未知数。这个教师早期职业发展项目的目标是开发公平和不确定性感知的文本分析方法,以衡量社会相关的主题,情感和跨文本主体的事件,以推断它们与变量的关系,如作者人口统计,健康结果和政治冲突。这些方法将更加准确,并且在出错时具有自我意识,适用于跟踪新闻事件或理解社交媒体情绪等应用。当前的文本聚合方法系统性地偏向于训练数据中的特质,并且受到感兴趣的社会变量之间自然语言处理错误的差异的干扰。此外,新的概率推理方法可以通过结合更丰富的结构化自然语言分析来帮助洞察,例如实体共指、事件解析或结构化情感分析。通过一系列的社会和健康科学的案例研究,该项目将开发更好的统计和语言模型,结合联合收割机概率生成和判别方法的文本建模。这些方法将更准确地衡量社会变量对话题、情绪和事件的影响,同时推断置信区间和其他重要的不确定性统计指标。最后,该项目将支持跨学科计算社会科学的教育和培训,通过本科生和研究生级别的研讨会,面向计算机科学,语言学,政治学和非裔美国人研究等领域的学生。该奖项反映了NSF的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
